We get below zero a couple times around here and my 89 does fine. I have a new carb on it but before that I never had a problem. Only fuel issues I have had was I got a carb from a junk yard and it only lasted a week before the jets went out. I got rid of the original carb because I got rid of the stepper motor wires during my rebuild. And the mechanical fuel pump went out on me a couple weeks back and I replaced it with an electric pump.

Make sure all the gauges work. Lights and what not. Check for leaks. Be sure to crawl under and check the frame for rust along with your floor boards. Jeep heaters are amazing so if it's working there's no problem keeping warm. Take a look under the dash and see what kind of mess your wiring is in. Make sure the 4WD works and Check the ebrake. The 4.2 and 2.5 are good engines. Treat them right and they will return the favor. Don't set your standards too high. It's not going to ride like your old Cherokee.

Rust rust and more rust. This one has the ole "rust cover" diamond plate over the rocker panels which is that many owners do to cover up rusted out tubs. The windshield frame looks to have been replaced also, another indicator of rust problems. Shame it has the carb instead of the fuel injection, but in compensation the hardtop looks good.
My '89 runs perfectly, and has since I bought it. It needed about $2k additional to the buying price to get the mechanicals sorted out and seats replaced,etc.
$3k (Canadian?) is a good price, but I couldn't make out the odo mileage.
The 19,000 kilometers listed in the owners ad is either a mistake or bogus.
